Extended Series® Breathers
Des-Case Extended Series® desiccant breathers combine the trusted materials and design of our Standard breathers with the check-valves of our VentGuard™ and HydroGuard® breathers, plus a new oil mist reducing feature, higher air flows and more than double the desiccant! These high airflow, long-lasting desiccant breathers are ideal for tank farms and large or remote applications.

Please Note: This is intended as a general guideline for sizing only; other considerations, such as: humidity level, frequency of air flow, ambient temperatures, and chemical compatibility are very important in sizing a breather properly. Larger applications and special circumstances typically require the most thorough analysis. Please contact Des-Case for assistance in sizing a breather.

As wet, contaminated air is drawn through the unit, multiple 3-micron polyester filter elements remove solid particulate, and the color-indicating silica gel extracts moisture. When air is expelled from the container, the top foam pad prevents oil mist from contacting silica gel or entering the atmosphere. Additionally, the breather is outfitted with a resilient nylon standpipe and polypropylene oil mist reducer to allow oil mist to coalesce and drain back into the reservoir, rather than compromising the desiccant. Six high-quality umbrella check-valves are located underneath the unit to isolate equipment from ambient conditions, prolonging breather life and protecting system integrity.
A pink breather means it has done its job keeping moisture out of your lubricants. Time to replace the breather with a new one.
